Bad: aliens that insist upon referring to human women as “feeeeemales”.

Good: aliens that insist upon dividing humans into binary categories, but the binary in question is based on something we’d regard as trivial and bizarre.

I got really emotional inspired by the The Golden Record, and decided to make this quick and messy comic about it.

What is a Rogue Planet?

A rogue planet (also termed a free-floating (FFP), interstellar, nomad, orphan, sunless, starless, unbound or wandering planet) is an interstellar object of planetary-mass, therefore smaller than fusors (stars and brown dwarfs) and without a host planetary system. Such objects have been ejected from the planetary system in which they formed or have never been gravitationally bound to any star or brown dwarf. The Milky Way alone may have billions to trillions of rogue planets, a range the upcoming Nancy Grace Roman Space Telescope will likely be able to narrow down.

See intricate cloud patterns in the northern hemisphere of Jupiter in this new view taken by NASA’s Juno spacecraft.

The color-enhanced image was taken on April 1 at 2:32 a.m. PST (5:32 a.m. EST), as Juno performed its twelfth close flyby of Jupiter. At the time the image was taken, the spacecraft was about 7,659 miles (12,326 kilometers) from the tops of the clouds of the planet at a northern latitude of 50.2 degrees.
